Excellent company and the person sent to service our older water softening system was quick and honest. We called Culligan's to come out and take a look at our water softening system, which hadn't been functioning since we moved in 5 years ago. They originally installed it, so they had our address already in their system with the water softener details on file. I was told there would be a trip fee of $145, plus whatever parts or extra service was needed at the time of the appointment. I was fine with that. Day of the appointment the service guy called me first thing in the morning and advised that he'd be at my house between 1:30PM-3:00PM. We had our back gate open from a different service and figured he would knock on the door when he got here. At about 5:00PM with no knock or call, I text the guy and he calls back immediately. It turns out that he was here at 2PM and because the gate was open, went directly to the water softener. He inspected it, ran a test, added some salt, and then performed a complete system restart on it. And then he left. He never knocked or called because the scope of the work was so minor that he felt it didn't warrant a full service call, so the didn't charge us. I cannot convey how much I appreciate his integrity! I also asked him whether he felt the system needed to be replaced, and he didn't try to sell me on a new system! The advice was that yes, the system is older but it functioned perfectly fine and didn't warrant replacement. It is so refreshing to encounter that level of honesty in a company and service person. Due to that alone, I would highly recommend using Culligan of Tucson if you need anything to do with water softeners!
